Marietta OH to Munising MI Road Trip: Ultimate Guide

This route follows the historic path of the first transcontinental highway, US-50, before cutting north through Ohio's Amish country and Michigan's Upper Peninsula. The drive from Marietta, Ohio's oldest settlement, to Munising, gateway to Pictured Rocks, covers 600 miles—a perfect two-day adventure.

Key fact: Marietta is the only city in Ohio that was settled by veterans of the American Revolution, and its layout was designed by Rufus Putnam, a general under George Washington. As you leave, you'll cross the Muskingum River on a bridge that once charged a toll for livestock.
